The Juniper EX switch must be configured to generate audit records containing information that establishes the identity of any individual or process associated with the event.

Description
Without information that establishes the identity of the subjects (i.e., administrators or processes acting on behalf of administrators) associated with the events, security personnel cannot determine responsibility for the potentially harmful event. Event identifiers (if authenticated or otherwise known) include, but are not limited to, user database tables, primary key values, user names, or process identifiers.

Determine if the network device generates audit records containing information that establishes the identity of any individual or process associated with the event. This requirement may be verified by demonstration or validated test results. Junos standard event log messages are configurable for time format, inclusion of logging facility and severity levels, and format. Setting "structured-data" automatically includes "explicit-priority" and "time-format year millisecond". Verify logging is enabled. [edit system] syslog { host { any info; structured-data; <<< Includes 'explicit-priority' and 'time-format' } host { any info; explicit-priority; <<< Includes logging facility and severity in standard format } file { any info; <<< Uses only standard format } time-format year; <<< Applied only to standard format } Note: In the example, events sent to the first external syslog server include the year and time is expressed in milliseconds. The second syslog server and the file both include the year, but time is expressed in seconds. If the network device does not generate audit records containing information that establishes the identity of any individual or process associated with the event, this is a finding.
